Patent GB-1041083-A (GB)
Title: Transparent organosilicon polymers
IPC: C07F7/08
Filed: 1963-06-19
Abstract: An optically clear, thermally stable, solventresistant organosiloxane-silcarbane polymer, in which each Si atome forms a member of an 8-membered ring of alternate Si and O atoms in which substantially every Si is attached to one monovalent hydrocarbon radical (h.c.), and in which substantially every Si atom is attached to another Si atom through an alkylene radical of at least 2 C atoms, can be made by contacting a first cyclotetrasiloxane, in which each Si atom is attached to both one monovalent h.c. radical free from aliphatic unsaturation and to one H atom, with a second cyclotetrasiloxane, in which each Si atom is attached to 2 h.c. radicals, one of which is unsaturated and the other is free of unsaturation, in the presence, as catalyst, of finely divided Pt, H2PtCl6 or the compound described and claimed in Specification 1,041,082. In a typical Example (1), a complex of H2PtCl6.6H2O and octyl alcohol was blended with an equimolar mixture of 1,3,5,7-tetramethyl - 1,3,5,7 - tetravinylcyclotetrasiloxane and the corresponding methyl hydrogen siloxane tetramer, and the resulting blend was allowed to stand at room temp. until the blend became viscous, when it was heated for 1/2 hr. at 50 DEG  C.  to yield a clear, hard, glass-like polymer. Where optical clarity is not required, fillers, e.g. C black ZnO, SiO2 (fume, pptd., aerogel), clay, whiting and slate flour, can be added.  Uses.-As insulation for electrical and electronic components; as optical elements in lens systems; as contact lenses; and for coating glass-tapes (see Division B2).ALSO:In Example (2) a glass tape was dipped into the viscous resin solution obtained by bending a complex of H2PtCl6.6H2O and octyl alcohol with an equimolar mixture of 1, 3, 5, 7-tetramethyl-1, 3, 5, 7-tetravinylcyclotetrasiloxane and the corresponding methylhydrogen siloxane tetramer and allowing the blend to stand (and thicken) at room temperature, excess solution was allowed to drain off and the coated tape was then heated for 1 hour at 50 DEG C. to yield a tape having a hard, clear, smooth coating of a siloxane-silcarbane polymer (see Division C3), in which the siloxane moiety is in the form of tetracyclosiloxane units.

Title: Improvements in or relating to fuel elements
IPC: G21C3/17
Filed: 1966-06-02
Abstract: 1,103,124. Fuel elements. GENERAL DYNAMICS CORPORATION. 2 June, 1966 [9 June, 1965], No. 24639/66. Heading G6C. A fuel element for a high temperature gascooled reactor comprises a top reflector 23, bottom reflector 25 and a plurality of intermediate fuel body sections 27, the reflectors and sections being of graphite and interengaged, e.g. by threads 39, 67. A circular bore 59 within the sections 27 and reflector 25 receives a square-section graphite spine 71, the spaces (37) (Fig. 3, not shown) between the spine and the bore forming coolant passages through which the coolant flows upwardly entering through holes 33 in the reflector 25 and leaving through a space 45 connected to holes 35 in the reflector 23. There are five body sections 27 and each of these sections together with the reflector 25 has a chamber or chambers receiving fuel material 61 in the form of coated fuel particles. Each particle has a fuel centre, e.g. of a mixture of uranium carbide and thorium carbide, and has an impervious coating capable of preventing the passage therethrough of all the fission products produced in the fuel material during its working lifetime. A triple coating may be employed comprising firstly an inner coat of spongy pyrolytic carbon, an intermediate coat of dense thermally conductive laminar pyrolytic carbon and an outer coat of dense thermally conductive columnar pyrolytic carbon. The reflector 25 and bottom section 27 each has a single annular chamber 75 receiving the fuel particles whereas the remaining sections 27 each has a series of sixteen bores 77 receiving the fuel particles. To even out the temperature gradient along the fuel element the cross-sections of the chambers and bores in the individual components 25, 27 are decreased in the direction from the bottom upwards so that the lower end of the fuel element has a greater proportion of the fuel. Plugs 7a prevent loss of fuel particles during assembly, these plugs being made of heat-decomposable material, e.g. polystyrene, which vaporizes as the fuel element is heated in the reactor. The fuel particles may be bonded together by coal tar pitch to prevent loss of fuel upon fuel element breakage. In a modification (Figs. 6-9, not shown) the body sections (97) loosely interfit by sliding spigot engagement and the structural integrity of the fuel element is assured by a threaded connection between the ends of the spine (99) and the upper and lower reflectors (93, 95). In other embodiments (Figs. 10-13, not shown) the spine is omitted and additional passages are provided in the body sections (147) for the fuel particles and coolant.

Abstract: 1482272 Sensing curvature of rolled metal section BOEING CO 11 July 1974 [27 July 1973] 24796/76 Divided out of 1482271 Heading G1M In the metal-bending, roll forming, system claimed in the parent Application (see Divisions G3 and B3), it is necessary to sense the curvature of the bent metal in more than one plane. The claims of the present application are restricted to the multiplanar sensing means per se. The sensing apparatus comprises a support member 41 which carries, through linkages 81 and 121, the multiplanar sensing assembly 33. The linkage 81 is such as to allow movement of the sensing assembly in a vertical plane but to prevent its rotation about the axis of workpiece feed. The linkage 121 and suspension means 171 co-operate to support the weight of the sensing assembly. The latter is a tube having two end plates 33, 35 each of which has an aperture 53 conforming with the cross-sectional shape of the workpiece. Each of the plates consists of a disc 51 held in a first ring 55 surrounded by successive further rings 57, 63 within the tubular housing 31. Twist of the workpiece is detected by the rotation of ring 55 coupled by gears 59 to rotary variable-differential transformer, RVDT, 61. Longitudinal and transverse bending of the workpiece are similarly detected by RVDTs 65 and 69 at one end of the assembly, either alone or in combination with like RVDTs 73 and 75 at the other end.

[Also in Group XXXV] A resistance and spark-gap device connected between one terminal of a circuit-breaker and earth, is provided with means whereby the flashover voltage of the spark-gap or gaps is reduced on tripping of the breaker so as to limit switching over-voltages. The normal flash-over value may be such that the device acts as a lightning arrester, or where a separate lightning arrester is provided, the device has higher normal flashover value. As shown, the spark-gap stack 13 in a vessel 14 is under pressure from the air cylinder 6 through a pipe 16 and valve 32 and an outlet valve 17 is closed. To trip the breaker a circuit 20 is energized by relay contacts 21 and the coils 18 and 19 operate servo valves 4 and 15. The former allows an operating blast of air to pass from the cylinder 6 to the breaker contact chambers 2, and the latter closes the valve 32 and opens the valve 17 so that the pressure falls in the vessel 14 and the flash-over voltage of the stack 13 is reduced (e.g. to normal power frequency test voltage of the breaker). Instead of being kept under pressure the gap electrodes may be moved closer together on tripping and the device may be used with other than air-blast circuit-breakers.
